SPECIFICATION forming part of Letters Patent No. 577,253, dated February16, 1897.

Application filed May l, 1895. Serial Nox 547,788. (No model.)

To all whom it may concern.-

Be it known that I, PAUL HAUPT, a citizen of the United States, residingat Baltimore, in the State of Maryland,have invented a certain new anduseful Improvement in Books, of which the following is a full, clear,and exact description. l

From the earliest times it has been found necessary to markdistinctively certain portions of the text. In manuscripts it Was doneby letters larger than others, or Written with a different ink, or byunderscoring, and the like. Similar' expedientshave been employed sincethe invention of the art of printing. All these expedients, however, areobjectionable in certain cases. The larger type is only serviceablewhere certain passages are to receive more prominence, as in headings,quotations, dac. Sometimes it is desirable to distinguish certainportions of the text without making one appear more prominent than theother. If there are but two portions to be distinguished, the use ofItalic alongside of Roman type works very well; but Where it isnecessary to mark a large number of different characteristics theemployment of a variety of type is objectionable. The use of differenttype on so extensive a scale makes the page less pleasing to the eye,and, moreover, it can very easily convey the idea that the size of thetype chosen indicates the relative importance of the respectivepassages, portions printed in larger or heavier faced type receivingundue prominence, while a smaller type will make a passage appear lessimportant. Besides, the printing with a variety of type is costly andrequires a large assortment of type, which makes it impossible for smallprinting establishments to employ the method, and even in the largestoffices there is not an adequate assortment of types to print a Greek,or Arabic, or Hebrew, or, in fact, any oriental text with nativecharacters in this way, or, for that matter, a transliteration of suchtexts by means of Roman type (or Italic) with the diacritical marks, (oraccents.) The printing of certain portions in different inks wouldobviate all these difficulties if it were possible to find nine or tendifferent inks that could easily be distinguished on a printed page,especially by artificial light.

The object of my invention is to provide a variorum or other. text, sofar as t-he letterpress is concerned, in black or other desired ink andblock out or mark the passages of different nature or originv by meansof distinctive colored backgrounds.

My invention consists in distinguishing the passages by colored portionsof the paper or surface of the sheet, so that the type of the passagesappear on a colored background, each passage of like nature having abackground of the same color.

The portions may be colored either before or after the letter-press isprinted. Inthis Way it is possible to use light transparent colors whichare easily distinguished, even by artificial 1i ght,without im pairingthe neatness and legibility of the printed text.

The invention is applicable to manifold type-written texts where it isnot feasible to employ a variety of type or a variety of ink.

The accompanying drawing represents a portion of a page of matterprinted in accordance with my invention,the various colors beingindicated by different surface lining, as named in the legend on thedrawing.

It is to be understood that in practice the colors themselves are used,the representations of colors by the lining or hatching on the drawingbeing necessarily adopted for the reason thatthe rules of the PatentOffice permit only black on drawings.

The matter represented in the drawing is a portion of the Book ofGenesis, chapter VI, describing the Deluge. In the account of the Delugeas contained in the said chapter there are two parallel narratives,which, though interwoven with one another, can be clearly separated.They are recognizable not only by a difference in their contents, butalso by certain peculiarities of style. For example,in the oneexclusively the word Lord is employed, while the other employs the wordGod. The uncolored portions represent the account of the Deluge7 in theso-called Priestly O0dethat is to say, the same post-exilic source towhich, for example, the account of creation as contained in Genesis Ibelongs. This document employs the name God. The lines tinted in lightblue contain the account of the Deluge taken from the older prexilicstory-book, in which God is called the Lord. It is the same IOO sourcefrom which the second account of creation as contained in Genesis Il istaken. The dark blue indicates an older stratum in this second document.The light-red marks indicate changes and additions made by the compilerof the Whole Work, who interwove the diiel'ent documents. The dark redindicates late glosses and interpolations of the text.

It will of course be understood that the sheet represented in thedrawing is selected merely as an illustration of my invention and thatthe selection of the colors and the facts which they are supposed toindicate are purely arbitrary matters.

By the use of the term booksin the title of this invention I do not Wishto be underof the same color, substantially as and for the purpose setforth.

In testimony whereof I have hereunto set my hand this 30th day of April,A. D. 1895.
